The state printing house in Soviet Baku wears its subject on its face: two vast stone pages spread across the facade, carved with a history of writing from Egyptian hieroglyphs to a Mayan calendar, with Georgian, Armenian, and Arabic script between them. Above the figures run mastheads of the Soviet press — Iskra, Pravda — and across the wall, in Russian and Azerbaijani, the most reproduced political slogan of the century: workers of the world, unite. The building still runs; the mosaic survives because nobody has renovated it since.
